Electric bag sealer



Dec. 28, N B HEN E ELECTRIC BAG SEALER Filed Dec. 14, 1936 J War 155 Hafiz WITNESS Patented Dec. 28, 1937 UNITED STATES PATENT OFFICE 1 Claim.

The invention relates to a bag sealing device and more especially to an electric bag sealer.

The primary object of the invention is the provision of a device of this character, wherein the open mouth end of a bag when filled can be conveniently sealed with dispatch, the mouth end of the bag being directed to an electric heating element so that the sealing medium carried at the mouth end of the bag can be softened whereby by pressing the open end closed the said end will be sealed.

Another object of the invention is the provision of a device of this character, wherein the same is actuated by the foot of a person when engaging the foot upon a pedal after the introduction of the open mouth end of a bag between an electric heater and a presser head, the latter being controlled by the pedal and thus the open mouth of the bag will be closed and sealed.

A further object of the invention is the pro-. vision of adevice of this character, which is extremely simple in its construction, thoroughly reliable and efiicient in operation, easily actuated, I

enabling the sealing of the bag with dispatch, and inexpensive to manufacture.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention and pointed out in the claim hereunto appended.

In the accompanying drawing:

Figure 1 is a front elevation of the device constructed in accordance with the invention.

Figure 2 is a top plan view partly in section.

Figure 3 is an end elevation.

. Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, A designates generally the device, in this instance comprising a flat base plate 5 preferably of substantially rectangular shape and made from metal having suitable screw holes for screws 6 which fasten the base plate 5 upon a table top, a portion of the same being indicated at forthe holding of the device in'a fixed position thereon.

Formed longitudinally of the base plate 5 close to one longer edge thereof, preferably the outermost edge, is a casing 8 having a flat work supporting top 9 and within this casing is an electric heating element ID in the form of a resistance coil embedded in insulation interiorly of said casing. Suitably built into the casing 8 and in association with the heating element I is a thermostat (not shown), being preferably located at l2, and the electric current feed line indicated at l3, respectively, which latter is equipped with a suitable cutoff switch (not shown).

Above the top 9 of the casing 8 is a presser head I4 having a corrugated work engaging face |5 while rising from the upper face of this head. are spaced hanger ears I6, each having an elongated slot I1 and these slots adjustably accommodate set screws I8, which are formed with winged heads l9 and are threaded in the arms of a double lever frame 2| formed with a pintle sleeve end 22 accommodating a hinging pintle 23 mounted in bearings 24 built upon the base plate 5 rearwardly of the casing 8 thereon. In this manner the double lever frame 2| is hinged for vertical swinging movement for the raising and lowering of the presser head M to and away from the casing 8 at the work face 9 thereof. 0

The frame 2| at an intermediate transverse brace 25 thereof carries a short length of a link chain 26 to which is attached a compression spring, a portion thereof being indicated at 21, and this spring is adapted to be attached to a 5 foot pedal (not shown) mounted at the floor beneath the table top and foot controlled so that by depressing the pedal the presser head M will be lowered for pressing closed a paper bag at the open mouth thereof bearing an adhesive substance when inserted between the faces 9 and I5, respectively, so that when the heating element I0 is active the mouth will be sealed close-d as the adhesive substance will be heated for the sealing of such mouth of the bag. The spring 21 exertsa tension on the frame 2| when the foot pedal is depressed for the exertion of pressure by the head |4'when moved toward the casing 8. The table top is formed with a suitable clearance opening 28 for the chain 26.

'Fixed in the plate are vertical guide pins 29 slidably engaged by the lever frame 2| while surrounding these pins are coiled tensioning springs 3|! for effecting the lifting of the frame 2| when foot pressure has been relieved from the pedal so that the head M will be raised with respect to the casing 8.

Forwardly of the casing 8 at the edge of the base plate 5 next thereto is an upstanding slotted bag guide 3|, the slot therein being indicated at 32 for accommodating the bag at the remote open mouth end thereof and directing the same onto the top 9 of the casing B for the sealing of the mouth end of such bag when the device is actuated.

The screws I8 adjustably connecting the head with the frame 2| enable the proper adjustment of the head to assure the sealing operation of the device. i

The pins 29 at their upper ends ,haveadiustable stops 33 limiting the upward swing of the frame 2|. 1

What is claimed is:

A sealing device of the\ character described Y comprising a base plate, a block-like heating element arranged on said base plate and having a flat horizontally arranged work engaging top, a presser head above said top and having a fluted work engaging face, a lever frame hinged to the base plate, winged screws adjustably attaching the said head to the frame for vertical swinging adjustment thereof, means operating said lever NORRIS B.
